Abstract

A Plasma Display Panel includes a front panel and a rear panel. The front panel includes a display electrode and a dielectric layer on a glass substrate. The rear panel includes a barrier rib and a phosphor layer on a substrate. The front panel and the rear panel are arranged to face each other, and the peripheries thereof are sealed to form a discharge space therebetween. The display electrode is constituted of multiple layers including at least a metal electrode layer containing silver and a glass material. A content of bismuth oxide (Bi 2 O 3 ) in the dielectric layer is in a range from 5% to 25% inclusive by weight, and a content of bismuth oxide (Bi 2 O 3 ) in the glass material of the metal electrode layer is in range from 5% to 25% inclusive by weight.

Claims (16)

1 . A plasma display panel, comprising:

a front panel including a display electrode and a dielectric layer on a glass substrate; and

a rear panel including an electrode, a barrier rib and a phosphor layer on a substrate,

wherein the front panel and the rear panel are arranged to face each other, and peripheries thereof are sealed to form a discharge space,

the display electrode is constituted of multiple layers including at least a metal electrode layer containing silver and a glass material, and

a content of bismuth oxide in the dielectric layer is in a range from 5% to 25% inclusive by weight, and a content of bismuth oxide in the glass material of the metal electrode layer is in a range from 5% to 25% inclusive by weight.

2 . The plasma display panel of claim 1 ,

wherein the display electrode includes a black layer containing a black material and a glass material, and

the black layer includes at least one of cobalt, nickel, copper, cobalt oxide, nickel oxide, and copper oxide.

3 . A plasma display panel, comprising:

a front panel including a display electrode, a light-blocking layer, and a dielectric layer on a glass substrate;

a rear panel including an electrode, a barrier rib and a phosphor layer on a substrate,

wherein the front panel and the rear panel are arranged to face each other, and peripheries thereof are sealed to form a discharge space,

the display electrode is constituted of multiple layers including at least a metal electrode layer containing silver and a glass material, and a black layer containing a black material and a glass material,

the black layer includes at least one of cobalt, nickel, copper, cobalt oxide, nickel oxide, and copper oxide, and

a content of bismuth oxide in the dielectric layer is in a range from 5% to 25% inclusive by weight.
